Okay, let's put to rest once and for all this misconception that Batman was the Golden Age's version of The Punisher.
Yes, in the very early comics, Batman killed. Batman first appeared in May 1939. The no-kill policy for Batman and Superman was instituted by editor Whitney Ellsworth. Do you know when Ellsworth instituted this policy?
It wasn't in response to the Adam West show.
It wasn't at the dawn of the Silver Age.
It wasn't as a result of the institution of the Comics Code Authority.
It was in 1940.
Roughly a year after Batman's creation, he stopped killing. And for the vast majority of his 77-year history, he has been depicted as a character who has a code against killing. That means about 1% of Batman's history depicts him as a killer.
If we're going to go with the first appearance as gospel for all other incarnations to follow, then going by that logic, we need to get rid of Batman's utility belt. That didn't come around until several issues later. We also need to do away with Alfred as a caring, intelligent, witty butler and instead portray him as nothing more than a fat, bungling amateur detective played purely for laughs (maybe we could get Jack Black to play him).
The next Fantastic Four movie, by the way? Sue Storm shouldn't be called the Invisible Woman in it. Instead, she needs to be the Invisible Girl. And she has to be portrayed as a moron who can never accomplish anything on her own, constantly forgets she's using her powers, and decides that testing different combinations of perfumes on herself will make her scent invisible to dogs.
